What's happening with touch screens is total mess due to car designers trying to circumvent regulations (e.g., can't have that screen in front of a driver, or projected over the windshield) - so they are forced to move it to a side, which makes operating it while driving more dangerous.
But even button's design is falling prey of it, with buttons hidden way below the top of the dashboard, made of the same size, etc. It takes forever to scan & find the right button (e.g. internal air) while driving.
And I don't see it as just some recent trend (although there's much more of it). Even 10-12 years ago, this way already a problem.
One example of stupidity: Toyota Sienna 2013 has brightness control for its media screen (which also shows back up camera) via a touch screen button. Turning brightness at night works ok - but then turning it back on during day light is impossible - nothing is visible on that dimmed screen!! Latest Toyota Sienna has all of the climate control buttons (8?) in 1 row, very low, of the same size, barely visible signs on them - recipe for disaster...
I wish these designers and execs would have their kids life depend on it - I wonder if that'd change their thinking...
